We have to replace our current pump (I believe that it’s a 1 HP Water Ace, also referred to as a “throw away” brand by one pool store) and I’ve been thinking that a dual speed would be the way to go. Our electricity is around $.12/kwh, so I’m not looking at the variable speeds.
I read in a thread from last year that “the Hayward SuperPump 1 HP Uprated SP2607X102S appears to be the most energy efficient two speed in-ground pump.” However, most of the advice on the forums seems to be “get the lowest HP possible.”
Should I keep trying to hunt down a 1/2 HP pump (or at least a 3/4 HP pump) or should I stick with the data and try to find a good price on the SuperPump? It seems like the 1/2 HP pumps are less common and less likely to be analyzed, so maybe the data just isn’t available to make a valid comparison. Or maybe it’s because they don’t make the 1/2 HP in 2-speed? If that’s the case, then my question is—what’s better, the single speed 1/2 HP or a dual speed 1 HP? We don’t have anything fancy on the pool, we even use a leaf bagger attached to the hose to vacuum. We MIGHT someday get some type of solar heating, which is why I was thinking it would be useful to have the option of a higher speed. Help?
